Universe

The system made up of all the matter and energy there is, including the galaxies, and their stars, planets, and moons. First there was a ball of matter/gravity and everything else. Then gravity fell off and that was thus the big bang

galaxies

A huge group of single stars, star systems, star clusters, dust, and gas bound together by gravity. Galaxies are like dust bunnies, every spec of dust is a star.

types of galaxies

spiral- shaped as a pin-wheel
elliptical- shaped as a flat ball
irregularly- strangely irregularly shaped

milky way

The name of our galaxy, a spiral galaxy that contains about 400 billion stars

astronomers - main facts, time alive, major contributions, where lived, where studied

...

Pythagoras

• Born about 570 B.C. in what is now Greece
• Made his discoveries while in Greece
• He recognized that the earth was a sphere and that the sun, moon, and planets had one of their own
• His astronomical concepts were acknowledged by Copernicus as a forerunner to his theory that the earth and other planets rotate in orbit around the sun
• Famous for formulating the Pythagorean theorem

Hipparchus

• Born 180 B.C. Turkey
• Credited with discovering the procession of the equinoxes, calculated size of earth, distance to sun and moon, many other observations
• Compiled first catalog of stars (brightness/position)
• His discoveries formed the basis of Ptolemy's system of astronomy.
• He was born near what is now Istanbul

Ptolemy

• Born 100 A.D. in Egypt
• Made discoveries in Alexandria, Egypt in about 150 A.D.
• Pointed out that the earth is spherical and rejected the idea that the earth moved, claimed that everything in the universe moved around or toward the earth's center, had small epicycles to make retrograde motion work.
• His system of astronomy was accepted throughout Europe until 1543, when Copernicus came up with the theory that the earth is a moving planet
• Ptolemy's map of the world encouraged Columbus to make his famous voyage across the ocean

Nicholas Copernicus

• Born in 1473 Poland
• Studied law and medicine in Italy but returned to Poland in 1606
• He proposed that the earth is a moving planet and that the sun is the center of the solar system
• He was the first astronomer to correctly describe the solar system and paved the way for Galileo and Kepler
• The Catholic Church refused to accept the heliocentric theory

Tycho Brahe

• Born in1546 Denmark
• He build an elaborate observatory on the island of Hven
• Developed a systematic approach for observing the planets and stars
• His observation were far more precise than previous astronomers and resulted in a much more accurate understanding of planetary positions, all done without a telescope
• He sighted a supernova in 1572 which helped disproved the ancient idea that no change could occur past the orbit of the moon

Galileo Galilei

• Born in Italy on February 15, 1564
• Called the founder of modern experimental science
• He made most of his key discoveries while in Pisa
• While teaching astronomy at the University of Padua he built his first telescope, in 1609, saw sun spots and suns rotation, moon craters, defended Copernicus
• His first astronomy related discovery was that the moon was not smooth but it was mountainous and pitted, also he discovered the four moons circling Jupiter in 1610, which he named Medicean Planets in hope of winning the Medicis the ruling family of Florence's favor

Johannes Kepler

• Born in 1571 Germany
• He worked in Prague
• Discovered three major laws of planetary motion
• Isaac Newton later used Kepler's three laws to arrive at the principle of universal gravitation
• Kepler was Brahe's assistant and when Brahe died the Holy Roman emperor appointed Kepler to be Brahe's successor

Isaac Newton

• Born in 1642 England
• He worked in England around Cambridge University
• He discovered the composition of white light; discovered how the universe is held together by laws of gravitation
• His theories on Gravity explained why the sun keeps the planets in their orbits and formed the basis for many discoveries and has helped expand our knowledge of the universe
• Three laws of Motion
• While in the countryside to avoid the plague, the concept of a universal force came to him when he was stuck in the head by a falling apple is not proven

William Herschel

• Born in 1738 Germany
• Settled in England 1757
• Discovered Uranus and its two brightest moons; discovered Saturn's moons; discovered the icecaps of Mars, several asteroids and binary stars; cataloged 2,500 deep sky objects; founded stellar astronomy, discovered nebulae, discussed stellar evolution
• He increase the size and understanding of our solar system
• He built a 4ft diameter mirror lens telescope which was the worlds largest until 1845
